LED grow lights are the most suitable ways to get your plants the light they need during their growing and flowering period. This is especially true if you are using hydroponic gardening techniques. These lights emit light at a wavelength which is ideal for plant growth. They use less electricity and are much cooler than traditional HID or fluorescent lighting and have a longer lifespan. It may cost more upfront, but over a long period, a best led grow light will save you a lot of money.

The Ultimate Buying Guide To Choosing The Best LED Grow lights

There are several factors to be considered while purchasing a LED grow light

Budget: LEDs are inherently more expensive than the usual grow lights. But they also save a lot of money over the longer period and are often more effective. Select an LED which is the best value for money for your needs and not necessarily the cheapest.

Type of growth: Depending on the type of plant you are growing, the choice of LED grow lights will differ. Refer to a gardening expert or online to find the right wattage, intensity and light spectrum required for your plants.

Area of growth: The coverage required often determines the size and number of LED panels you need to buy. A quick rule of thumb as suggested by most experts is 25-30 watts of power per square foot of growth area. But if you are growing low light plants, then 16 – 20 watts per square foot is a better calculator. While installing these panels ensure that light coverage overlap. Also look at whether there is secondary optics included. Check also the angle of the beam to ensure you get the best coverage and impact across the area covered.

Names: Be careful of buying based on just the name of the light. Most lights have wattages like 300 w or 800 w associated with their name. Please check the actual output before buying.

Light Spectrum: Look at the range of light spectrum required for your plants as per the expert. Buy a light with adjustable output spectrum which will help you tailor your light according to the growth phase of your plants. These changing lights will help mimic the seasonal changes. Look at the PAR value required by your plants and match it to your LED light.

Cooling System: One of the advantages of LED grow light is that it is cooler than regular lights and so does not require additional cooling mechanisms like air conditioning and fans in the growing area. Ensure that your panels have good fans and heat sinks.

Fixtures: Which are mounted on a metal core printed circuit board that can operate at higher temperatures.

Warranty and guarantees: Reflect the company’s confidence in its products. Look for products where company’s offer warranties which are at least as long as the lifespan of the LEDs.

Be smart and buy the best LED grow light which gives you the best value for the money being spent.
